Specification of Letters Patent.

Patented July is Application filed December 13, 1921; Serial No.522,6?4l.

To all whom it may concern:

ing bicycle and auto canvas, a textile fabric having relativelyfew weftthreads. Heretofore it has been customary in Weaving such materials toWind the warp threads upon warp beams and then introduce them into theloom. The substitution of a full warp beam fol-an empty onenecessitatedv stop ing of the loom, resulting in loss of pro uct-ion.Moreover, the-preparation of the warpbeam required the help of a skilledworkman, the weaving master, thereby adding to the cost of production.Furthermore,

it often happened that the first tissue was unserviceable and the lastportion of the warp, the so-called drum, was lost. Besides, the lastportion of the warp threads was lost during warping and beaming up;

The above mentioned drawbacks are avoided by the present inventionaccording to which the warp threads, Without being beamed up, are fedfrom one or more creels of novelconstruction to a novel form of tensiondevice. The advantages of the invention are many. By reason of theomission of preparatory machines and the weaving beams, fewer workmenare required and there are practically no losses of material and theworking-is continuous owing to the r 2 to a feeding or brake device,consisting.

fact that the empty bobbins of the warp threads ,niay begraduallyreplaced by full bobbins during weaving.

The drawings illustrate one embodiment of the invention by way ofexample.

Fig. 1 shows schematically a sideelevation of thedevice with the loom.

Fig. 2 is a plan view of this device, with out the loom.

Fig. 3 shows on a larger scalea front elevation of a thread frame withsome bobbins and thread guides mounted on the same.

According to the invention the Warp threads of the bobbins, placed uponthe thread frames 1, are fed through the reed of a roller 3, having acovering of a fricti0n-material, e. g. felt, with front and back tensionrollers 4 and 5., This device is conat both sides the planes of V-shapsecured to the vertical frames 1, so that the structed in such a manner,that the wai'rp threads are subjected to suiiicient friction, Whilehowever it is still possible. to draw through each thread individuallywithout danger of rupture, which is important in repairing threads andremoving eventual mistakes in the threads. From here they pass over thesmoothing beam. 6 to the loom, indicated as a whole by '2 in Fig. 1. Thereed 2 is mounted more or less resilientl e. g. on a brace 8. The feltcovered roller 3 acts as a feeding or brake device, so that an equalfeeding of the warp threads is ob tained.

The resilient suspension ofthe reed con tributes to the warp dischargeand decreases the danger-of rupture.

As appears fromFi 2 the frames may be verylong so that t e height may beso small, that all bobbins are within the reach ofa boy or girl whereasnevertheless a very largeiumber of bobbins may be mounted on the frames.V

For obtaining an easy substitution of emptybobbins by full ones thebobbin pins are placed perpendicular to ed carriers 10, which arebobbins 12 are-disposed under an angle of about 455 with respect to thevertical plane.

From the bobbins the warp threads run through eyes in. the thread guides13 in such a manner, that each thread is guided in its own eve.

{By this device it results that in the case of a rupture of a thread,the broken thread. can be found directly and repaired by the assistantwithout interruption of the worlr.

l. l/Veaving apparatus, comprising a ten" sion device and a plurality ofspaced creole arranged in front ofsaid tension device, said tensiondevice comprising a pinrality of cooperating rollers and a reedyieldingly supported in front of said rollers, and each of said creelscomprising a carrier extend ing radially with respect to said tension device, and a row of bobbin pins supported by said carrier.

2. Weaving apparatus, comprising a tension device, and a plurality ofspaced creels arranged in front-of said tension device, said tensiondevice comprising a plurality of cooperating rollers and a reedyieldingly supported in front of said rollers and each of mg a coveringof friction material, tension rollers having a relatively small diameterin comparison to the diameter of the friction roller, said tensionrollers being arranged at the front and back of said friction roller andin close proximity thereto, a reed in front of said friction roller, andyielding means supporting said reed from said frame. In testimonywhereof I allix my signature.
